cmake: Invoke 'python' instead of py scripts directly

Python scripts should be executed indirectly by the python
interpreter, not directly in a CMake COMMAND. This is for portability
reasons.

Directly executing a python script depends on non-portable shebang
logic and/or "default application" behaviour.
